Abstract
A modular escutcheon for a door lock including a plurality of covers. Each higher cover may progressively project outward from the surface of a door more than the covers below. Top and bottom edges of adjacent covers abut to form a joint, which may be partly or completely concealed resulting from the outward projections of higher covers. An escutcheon system may be provided that includes interchangeable parts, for example, there may be several different intermediate covers for use with the same lower and upper covers, or different upper covers that may be used in the same position. A variety of lock operating devices may be provided with the different covers to achieve different systems.
Claims27
An escutcheon for a lock for a door, the escutcheon comprising:
- a first cover including a first facing having a front surface and a back surface, sidewalls extending therefrom terminating in edges, and first and second ends, the first cover facing spaced a maximum, first distance away from the first cover sidewall edges;
- and
- a second cover including a second facing having a front surface and a back surface, sidewalls extending therefrom terminating in edges, and first and second ends, the second cover facing spaced a maximum, second distance away from the second cover sidewall edges, the second distance being greater than the first distance such that when the first cover sidewall edges and second cover sidewall edges are coplanar the second cover facing extends beyond the first cover facing, wherein the first cover second end and the second cover first end are adapted to abut in close and complementary registration to form a joint,
- wherein one cover is adapted to pass a latch operator.
An escutcheon for a lock for a door, the escutcheon comprising:
- a lower cover having a surface and a top edge, the lower cover adapted to be mounted to the door such that the surface is spaced a maximum, first distance away from the surface of the door and having a top edge;
- an intermediate cover having a bottom edge, a top edge, and a surface, the intermediate cover adapted to be mounted to the door such that the surface is spaced a maximum, second distance away from the surface of the door, the second distance being greater than the first distance, and the intermediate cover adapted to be mounted to the surface of the door above the lower cover such that the bottom edge of the intermediate cover and top edge of the lower cover are in close and complementary registration to form a joint;
- and
- an upper cover having a surface and a bottom edge and adapted to be mounted to the door such that the surface is spaced a maximum, third distance away from the surface of the door, the third distance being greater than the second distance, and the upper cover adapted to be mounted to the surface of the door above the intermediate cover such that the bottom edge of the upper cover and top edge of the intermediate cover are in close and complementary registration to form a joint, and
- wherein one cover is adapted to pass a latch operator.
